0800 475 7458 - call is a HOAX... tried returning call and was automated voice told number not recognised! These people have no shame
Although call was initially very noisy and hard to hear, I was being asked about information relating to car accident I had in last 2 years..so assume they are after personal information to steal money and/or identity... as I said NO SHAME! >:-(

Soo strange. This number called me today also (5/18/2016). It was a very very slow robotic sounding female voice, very hard to understand, essentially saying that they are with the IRS and you have to call them immediately and that it is a 'time sensitive' matter. So, the funny part is they called FROM 4153014726, but the number the recording tells you to call back is 4152014726. That number just goes nowhere for me.
